AI 中文摘要
我们首次在无任何微观截断的情况下，推导了含库仑相互作用的经典粒子的二维弗拉索夫-泊松方程。该证明依赖于我们近期提出的平均场极限的双层次方法，结合基于动力学正则化效应的线性化关联上的双BBGKY层次的精细分析。该结果更一般地适用于任意奇异相互作用力$K\in L^{2-\eta}_{loc}$（其中$\eta>0$足够小），且在任意维度下成立，还可扩展至布朗粒子。只要平均场解足够正则，该结果在时间上全局成立。
英文摘要
We obtain the first derivation of the 2D Vlasov-Poisson equation for classical particles with Coulomb interactions without any microscopic cutoff. The proof relies on our recent dual hierarchical approach to mean-field limits, together with a refined analysis of dual BBGKY hierarchies on linearized correlations, based on kinetic regularization effects. The result holds more generally for arbitrary singular interaction forces $K\in L^{2-η}_{loc}$ with $η>0$ small enough, in any dimension, and it extends to Brownian particles. It holds globally in time as long as the mean-field solution is regular enough.
